Kishinouyea pond three-harvest raising technology

Abstract

The invention provides a kishinouyea pond three-harvest raising technological method, belonging to the field of aquaculture industry. The method is characterized in that the first batch of kishinouyea seedling is heated and raised in March or April 1, and is stocked to raise on May 1st so as to harvest first batch of kishinouyea at the end of June; low-temperature controlled kishinouyea scyphistoma is selected as the second batch of kishinouyea seedling, is heated and raised atnatural water temperature on May 15th, and the second batch of kishinouyea can grow to12cm, the large-sized seedlings can be stocked, to harvest the second batch of kishinouyea at the end of August; and low-temperature controlled kishinouyea scyphistoma is selected as the third batch of kishinouyea seedling, is heated and raised with natural water on July 15th, and the third batch grows to 12cm large-sized seedlings can be stocked to harvest the third batch of kishinouyea at the end of October. By utilizing the technology provided by the invention, the kishinouyea can be raised in ponds in coastal areas of China in three seasons per year, so that the production cost is saved, the survival rate of the kishinouyea scyphistoma is improved, the breeding rate of foreign algae is reduced, the kishinouyea raising benefit is greatly improved, the market requirement is met, and the technology is suitable for popularization and application.

Description

technical field [0001] The invention belongs to the technical field of marine organism cultivation, and in particular relates to a three-crop cultivation method in a jellyfish pond a year. Background technique [0002] Jellyfish Rhopilema esculenta (Kishinouye) is a large edible jellyfish with extremely low fat content, rich in protein and inorganic salts, and high economic value. occupied an important position. Pond cultured jellyfish has the advantages of less investment, quick results, and large profits, and has received extensive attention from coastal fishery scientists and farmers in my country. [0003] At the beginning of this century, the natural output of jellyfish decreased, the price rose rapidly, and the export benefit was high. From 2000 to 2005, the scientific research project "Research on Ecological Breeding Technology in Jellyfish Pond" explored by researcher Zhang Xijia of Shandong Provincial Oceanic Fisheries Research Institute was successful, so pond far...

Problems solved by technology

As the jellyfish pond culture technology has not yet been perfected, only one or two crops can be cultivated, wasting the effective breeding space, the yield and comprehensive benefits of the jellyfish pond population cannot be fully utilized, and the large-scale promotion of jellyfish culture urgently needs technical support and technology popularization
